Been a while since the last time. I had to make a few adjustments to the Point Attractor GH User object so that it outputs tree or branched data. The reason for this update is this discussion on the GH forum, which then led to a really impressive jewellery design, more specifically a wireframe bracelet.

Ifigenia Lambrou from Ikreate was kind enough to share some pictures of the final product of the algorithm using the Point Attractor. Here is a short description of the project named Parametric Wireframe Bracelet.

“Ikreate is a design studio founded in 2012, that focuses in jewellery and home decoration designs using rapid prototyping methods. The idea of designing parametric jewelleries through Grasshopper was a challenge due to the possibilities available plus the multiple outcomes. “One of a kind” jewellery idea was into our field, so as the ability of personalising them, according to the user. Parameters would alter the result each time changed.

The concept was to produce a magnetic field, a field of attractors, that could have the ability of affecting the structure of a geometry. In particular, a torus was chosen so as to be used for a bracelet. Torus geometry translated into a number of division curves in u and v. Alteration in the points, used as attractors, was deforming the curves, the structure of the torus. During the final phase – production of a wearable geometry – physical flexibility was necessary to be given at the model. Besides the material used during printing procedure, the combination of the parameters, number of division+radius of the pipes, gave an extra flexibility to the model.”

I have made an attempt to re-create this result by also altering the overall morphology of the toroid shape. I am attaching a snapshot of grasshopper definition below. Please mind that you have to grab the updated GH user componet for Point Attraction from here . Enjoy.

Hi. Can I ask how you are connecting a normal to a surface? Isn’t it a vector? I tried it out just in case I was wrong, but it does indeed show an error at surface cp “Data conversion failed from vector to surface” I hope you can help me. Thanks.
